新疆褐牛犊牛补饲试验效果分析

Effect Analysis of Supplementary Feeding Experiment on Xinjiang Brown Calf

[目的]为探讨新疆褐牛犊牛补饲对其生长发育以及经济效益的影响,[方法]试验选取新疆褐牛犊牛20头,分为试验组和对照组,试验组犊牛在哺乳的基础上补饲精料,4月龄断奶,对照组分阶段饲喂,6月龄断奶。同时测定4月龄、6月龄的体高、体斜长、胸围、管围、体重并计算日增重和经济效益。[结果]结果表明,与对照组相比,4月龄试验组在体高、体斜长有着明显的提高,6月龄试验组在体斜长、胸围、管围、体重和日增重也有着明显的提高,但均为达到显著水平(P<0.05)。经济效益分析结果表明,通过犊牛早期补饲可明显提高农牧民收入,节约饲养成本,相比传统饲喂方式每头犊牛饲养至6月龄可节约成本342元。[结论]综上,早期补饲对可提高新疆褐牛犊牛的生长性能,对改善养殖经济效益,提高经济收入有着显著的效果。

[Objective] In order to explore the effects of supplementary feeding on the growth and development and economic benefits of Xinjiang Brown calves. [Method] 20 Xinjiang Brown calves were divided into experimental group and control group. The calves in the experimental group were supplemented with concentrate on the basis of lactation, weaned at 4 months old, and the control group was fed stages and weaned at 6 months old. At the same time, the body height, body length, chest circumference, cannon circumference and body weight were measured at the age of 4 and 6 months, and calculated the daily weight gain and economic benefits. [Result] The results showed that compared with the control group, the body height and body length were significantly improved in the 4-month-old experimental group, and the body length, chest circumference, cannon circumference, body weight and daily gain were also significantly improved at the 6-month-old(P<0.05). The economic benefit analysis results showed that early supplementary feeding could significantly improve the income of farmers and herdsmen and save feeding cost. Compared with the traditional feeding method, the cost raising each calf to 6 months old could save 342 yuan. [Conclusion] In summary, early supplementary feeding could significantly increase the growth performance of Xinjiang brown calf, improve the economic benefits of breeding and increase the economic income.
